Odour Monitoring Report – Week Commencing 11th August 2025
Odour monitoring was undertaken across a range of locations to assess potential nuisance and identify any links to landfill gas or odours originating from the landfill site. A total of 89 observations were made, with results broken down by all locations, high sensitivity receptors, and low/medium sensitivity receptors.
Overall, the findings confirm that landfill operations did not contribute to odour impacts at any of the monitored locations over the period.
All Locations
Across all locations, the overwhelming majority of observations (82.0%) recorded no odour. The remaining detections were primarily everyday, non-landfill related odours: sewage (7.9%), cut grass (4.5%), perfume (4.5%), and sewage mixed with perfume (1.1%). Importantly, there were no detections of landfill gas or odour attributable to the landfill site.
High Sensitivity Receptors
At high sensitivity locations, results were even more reassuring. Of the 57 observations recorded, 94.7% noted no odour. The very small number of odour detections included cut grass (1.8%), perfume (1.8%), and sewage (1.8%). All of these odours are environmental or industrial in origin and unrelated to landfill activity. No landfill gas was detected.
Low/Medium Sensitivity Receptors
At low and medium sensitivity locations, 19 of the 32 observations (59.4%) recorded no odour. The detections here were somewhat more frequent but again entirely unrelated to landfill gas. Sewage was the most common odour (18.8%), followed by cut grass (9.4%), perfume (9.4%), and combined sewage and perfume odour (3.1%). These odours are consistent with local environmental and industrial sources.

Conclusion
Overall, the dataset for the period clearly demonstrates that the vast majority of monitoring locations recorded no odour, and those that did were attributable to everyday, non-landfill sources. Crucially, there were no detections of landfill gas or odours from the landfill site across any location category, including high sensitivity receptors. This indicates that landfill operations did not contribute to any odour impacts in the monitored area for the period.
